To all whom it may concern:

Be it known that I, JOHN W. HUBLEY, a citizen of the United States,residing at Washington, District of Columbia, have mvented certain newand useful Im rovements of 'which thefo owing is a specification.

This invention relates to beer coolers.

The ordinary beer cooler coil which is usually made ofblock .tin issubject to numerous objections, among which may be difficulty incleanwhich contaminate the beer through, diflicult in detaching andremov-v ing it from its p ace in the cooler box, and

i the old type of continuous pip its pitting and disintegration by theammonia in the ice water. Among its other defects is its relativelygreat expense and necessity for comparatively frequent renewal, asidefrom being insanitary. I

My invention has for its object theprovision of a beer cooler of simple,strong and durable construction which may be inexpensively manufacturedand installed, either originally when the beer dispensing apparatus isput in, or spbsequently to supplant e coil cooler. A further object isto provide an improved beer cooler which can be readily taken apart andquickly washed and cleaned, will not be liable to injury, as is the casewith cooler coils, will not be subject to disintegration by the actionofammonia, will at all times afford a free and easy circulation for thebeer and the ready disposal'of the ice about the beer cooler and theflow or circulation of the ice water therethrough.

Further objects are to provide an improved beer cooler made of separableparts of new construction having new means for beer.

the connection together-thereof which permits rapid and easyv asseinblin'or separation and prevents any leakage o the beer.

A still further object is to provide a beer the inlet thereof arrangedin relation to e cooling coils or channels so'that there is nointerference with the free admission of the beer under the usualpressureand hence no gurgling or choking or back pressure which would interferewith the drawing oif of the .Havin in view the foregoing obj ectsandothers w ich will more fully; appear from the following description, thenvention consists, first, in a beer cooler composed of inner and outershells one of which has spiral grooves constituting coils or channelsfor the passage of the beer, the inner shell being tightly fitted intothe outer shell and inlet and outlet means being provided for theadmission and outflow of the beer; second, in a beer cooler of the classset forth having the inner shell exteriorly tapered andthe outer shellinteriorly tapered, the inner shell being provided with spiral exteriorgrooves constituting a beer circulating coil or channel when the shellsare fitted together, together with an inlet and an outlet for admittingthe beer to the spiral channel and taking it 011' therefrom, the innershell being hollow and both shells arranged so that the ice and icewater may circulate through the inner shell, whereby the beer is subjectto cooling action at all points; third, by providing, in a beer cooler,new means V rable shells combined with new means for drawing the shellstightly together without interfering with adaptability for readyseparation for purposes of desired; fifth, in the provision of a beercooler of novel construction having an inner removable shell providedwith beer circulatingchannels and an exterior shell adapted forconnection to the beer supplying and beer dispensing means, which may.be readily installed' in any beer dispensing apparatus in use insubstitution for the ordin'ary' cooling coil, and, vision of parts soarranged that they may be taken apart and cleaned without interferingwith 1 the practically continuous use of the cooler or the dispensing ofthe beer. forms, certain ones of fully hereinaftenand are modificationsand which are set forth which- Figure 1 is a verticalisection showingthe. 2, a detail vertical of .Fig. 3; Fig. 5, an exterior view of thefurther, in the proan'improvedcooler havmg .its-

The ice box mg apparatus is shown at 1, the dispensing faucet or spigotat 2, the keg or cask at 3. and'the drawing oil or beer pipe at 4:,which is valved, as usual, so that of beer to the cooling apparatus maybe cut ofi, as for instance, when the cooler is being cleaned. The usualoverflow pipe appears of any preferred metal-not shown in Fig.

Referring first to Figs. 1. and 2, 6'designates an outer metallic shellwhich may be susceptible to ammonia or other acid to which it would besubject, the interior of the shell being-tapered from its upper to itslower end, its lower end being more abruptly tapered, as 2, at 7 Thebase of the outer shell. is provided with supporting ;legs 8, tom of theice box to permit the free circulation of the ice water through thecooler. Fitted into the interior of the shell 6 is an inner removableshell 9 whose exterior, and

The outer sur-; provided with oove or channel of 5 at 10. Both the areofsolid metal thoughnot necessarily, constructed of Thompson metal. Thelower end of the inner shell 9is adapted to fit withinthe tapered-orconcaved part 7 its upper to its lower end. face of the inner shell-9 ismner and" the outer shell and hasian annularbead or flange 11.Surrounding the inner shell and located between the bead 11 and. thelower end of the 10 is a 'gasket 12- of any preferred or ordinary formwhich snuglyfits interior of the outer shell and, the inner shellinto-the outershell, this gasket is compressed and affords a liquiddightjoint between the shells at their lower parts. The dimensions and taperof the shells'are such that the inner shell wedges tightly into theouter shell so that each and every crest 13 of'the spiral channel 10fits snugly against the interior is no possibility onepart of the partthereof, but it is forced to circulate around'the inner shell andbetweenit and the outer shell before it can finally pass out through thepipe 14 which. dehvers it. to the spigot or faucet 2. The lower .partofthe outer shell is provided with an internally screw-threadedpipecouposed the. supply 1 the cooler is raised above the botis taperedfrom .into the coupling 26,.or at least pling 15 for the connection ofthe pipe 16 which admits the beer to the cooler.

J The upper end of the inner shell 9 is enlarged to form a flanged head17 and interbetween this head and the flanged head 18 on the outer shellis a compressible gasket 19 of any preferred or ordinary construction. Iprovide on the head 17 handles 20 which enable the bar tender or otherattendant to obtain a free grasp on the inner shell and permits the easylifting of the innershell out of the outer shell. To clamp the inner andouter shells firmly togetherand to compress the, gaskets 12 and 19, Iprovide cam clamps which are pivoted to ears 21 on the head 17 and whosehooked parts 22 are adapted to engage under the flange 18. These clampsmay be two or more in number and 'afl'ord a means for quickly and easilyclamping the -innerand outer shells together with such pressure that theinner shell is firmly wedged into the outer shell and the gaskets arecompressed and prevent any leakage.

' In'the form shown in Figs. 3, 1 and 5,

the base of the outer shell is provided with nclined or wedge grooves 23and the inner shell has inclined to be engaged with said grooves, thearrangement being such that the inner .shell may be inserted into theouter shell and given a twist tocause the lugs 24-,to enter the grooves23, thereby clamping the inner and outer shells together at theirlowerends and drawing the inner shell down into the outer shell, suchclamping action supplementing that afforded by'the parts 21, To removethe inner shell, it is only necessary, in this form of release theclamps 21, 22 and then to grasp the handles 20 and impart a twist to the.inner shell, whereupon the inner shell may be readily removed.

' In the form shown in Figs. 7, 8 and 9, the

lower part of the cooler is of the construe tions'hown in Figs. 1 and 2,exceptthat the lowermost part 25 of the spiral beer circulating-\channel 10 is arranged tangentially or wedge lugs 24 adapted theinvention, to first and the coupling 26 for the pipe 16 may be alsoarranged tangentially, 8, or it may be arranged either instance,

asv shown in Fig.

the delivery of the beer is in vertically, but in a tangential directioninto the lowest groove of'the channel 10. This arrangement prevents anyback pressure on the beer or interference Withfylts free entry into thechanml 10. In consequence, the beer cannot choke as it enters the coolerand its un'tramneled circulation in the channel 10'and exit I v pipe 17is assured. 3T0 insure the absolute allnement of the part 25' with thedelivers the beer into the channel 10, I provide on'the inner shell 9 alug 27 adapted to fit in a cor-respondingnotch in the inner the part 26"which upper edge of the. outer shell. By dropping the lug in this notch,the parts 25 and 26 are assured of alinement. To insure a firm clampingof the inner and outer shells together and the wedging of the innershell in the outershell, as well as the compression of the gasket, Iprovide in this form of the invention a bridge 28 extending across theinner shell and preferably integral therewith and a detachable yoke 29whose hooked ends 30 engage under the flanged head 18, as also a handscrew 31 threaded through the yoke and having its tip adapted to bear onthe cross piece 28. On releasing the screw 31, the yoke 29 may beremoved by tilting and the inner shell may be taken out. The handles 20may be provided on the inner shell, as previously.

In all forms of the invention, when it is desired to clean the cooler,the valve in the pipe 4 is turned to cut off the supply of beer and theshells are unclamped from each other and the inner shell removed. The,spiral beer circulating channel 10 may then be readily cleaned andthesmooth interior of the outer shell washed, after which the innershell may be quickly reinserted within and clamped to the outer shell sothat there is practically no interference with the dispensing of thebeer from the spigot 2.

My invention is not only adapted to be installed originally in a beerdispensing apparatus, but it may be quickly and easily substituted forthe old style type of continuous pipe coil at small expense and withlittle labor. c

I am aware that various modifications might be.resorted to in carryingout my invention and I, therefore, lay claim to all forms falling Withinthe spirit'and scope of the invention.

Having thus described my invention, what I claim asnew and desire tosecure by Letters Patent, is

1. In a beer cooler, the combination of an outer shell having a taperedinterior, a re-' movable inner shell having a tapered exterior providedwith a liquid circulating channel, said inner shell being adapted to fitthe interior of the outer shell and having a shoulder or bead on itssmaller end, means for securing the shells together, one within g theother, means .for admitting liquid to the channel, means for taking theliquid off from said channel, a compressible gasket interposed betweenthe two shells at the larger end of the cooler, and a' compressiblegasket surrounding and carried by the smaller end of the innershell andheld by the bead thereof, said last named gasket bearing against theinterior of the outer shell.

. 2. In a beer cooler, the combination ofan outer shell having a taperedinterior terminating in a more abruptly tapered interior at its endpart, a removable inner shell havinga tapered exterior provided with aliquid circulating channel, said inner shell being adapted to fit theinterior of the outer shell and having, a shoulder or bead on itssmallerend, means for securing the shells together, one within the other, thesmaller end of the inner shell being received in the abruptly taperedinterior part of the outer shell, means for admitting liquid to thechannel, means for taking the liquid oil from said channel, acompressible gasket interposed between the two shells at the larger endof the cooler, and a compressible gasket surrounding and carried by thesmaller end of the inner shell and held by the bead thereof, said lastnamed gasket bearing against the abruptly tapered interior part of theouter shell.

- 3. In a beer cooler, the combination of an outer shell, an inner shell.fitted into the for said channel, a lug onone of the shells,

the other shell being provided with means adapted to engagelthe lug whenthe shells are fitted together, said devices being ar- .r

ranged to insure that the liquid admission means willbe in position todeliver the liquid to the'channel, means for taking off the liquid fromthe channel,'and means for securing the shells one within the other.

In testimony whereof, I hereunto afiix my signaturein presence of twowitnesses.
